The App

We are collecting information on the phone's acceleration and magnetic field. We wish to understand how electronic devices influence their environment, and how better than with the most readily available devices out there: our phones.

In return, we show you the readings we have in two maps: one where you can see only your readings and another where you can see a more general picture of the values we've collected from everyone.
